Specific Hazards: Decomposes at high temperatures giving off antimony oxides, potassium oxides, carbon oxides, and toxic fumes
Protective Equipment: Firefighters wear full protective gear, self-contained breathing apparatus
Firefighting Advice: Approach from upwind, avoid inhalation of toxic fumes, keep unaffected containers cool by spraying with water
Personal Protection: Wear chemical resistant gloves, safety goggles, NIOSH-approved respirator if powder becomes airborne
Environmental Precautions: Avoid dispersing dust, prevent runoff into drains or water bodies
Spill Clean-up: Ventilate area, sweep up carefully with minimal dust generation using non-sparking tools, containerize for proper disposal, clean area thoroughly
Decontamination: Wash spill area with water after pickup, avoid letting residue enter environment
Safe Handling: Minimize dust, avoid ingesting, do not get in eyes, wash hands before eating or drinking, handle in well-ventilated setups, use fume hood for weighing powders
Safe Storage: Store cool and dry, in original tightly closed chemical-resistant container, away from acids, oxidizers, moisture
Incompatible Materials: Strong acids, strong oxidizers, reducing agents, sources of ignition
Other Precautions: Keep away from food and drink, label containers clearly, restrict access to trained lab staff
Exposure Limits: OSHA/NIOSH PEL for antimony: 0.5 mg/m³ (as Sb)
Engineering Controls: Lab fume hood, local exhaust, use closed systems for transfers
Personal Protective Equipment: Lab coat, chemical splash goggles, nitrile or neoprene gloves, approved respirator for dust
Hygiene Measures: Wash hands and face after handling, don’t touch face with contaminated gloves, do not eat or drink in work area
